Description
Technical field
The present invention relates to wireless communication system, more particularly, relate to and provide and receive service method on the downlink sharied signal channel in wireless communication system.
Background technology
Fig. 1 is the block diagram of network configuration of the Universal Mobile Telecommunications System (UMTS) of the asynchronous IMT-2000 of 3GPP system.With reference to Fig. 1, UMTS mainly comprises subscriber equipment (UE), UMTS Terrestrial radio access network (UTRAN) and core net (CN).UTRAN comprises at least one RNS (hereinafter abbreviating RNS as).RNS comprises a radio network controller (RNC) and at least one base station (Node B) of being managed by RNC.In a Node B, there is one or more sub-district at least.
Fig. 2 is the system assumption diagram of the Radio interface protocols between UE (subscriber equipment) and the UTRAN (UMTS Terrestrial radio access network).With reference to Fig. 2, Radio interface protocols comprises physical layer, data link layer and network layer in vertical direction.In the horizontal direction, Radio interface protocols comprises the user's face that is used for data information transfer and is used for the chain of command that signaling is transmitted.Protocol layer among Fig. 2 can be divided into ground floor (L1), the second layer (L2) and the 3rd layer (L3) (for example following three layers of the OSI(Open Systems Interconnection) master pattern of this area well-known).Each layer among Fig. 2 carried out following explanation.
Physical layer (PHY) is a ground floor, and it uses physical channel to provide information transfer service to the upper strata.Physical layer (PHY) is connected to medium access control (MAC) layer that is positioned on the physical layer PHY by transmission channel.By transmission channel Data transmission between MAC layer and PHY layer.In addition, by physical channel between different physical layers, more particularly, Data transmission between the physical layer of the physical layer of emitting side and receiver side.
The MAC layer of the second layer provides service by logic channel to Radio Link control (RLC) layer that is positioned on the MAC layer.The reliable transfer of data of rlc layer support, and can cutting apart and combine (concatenation) and operate the RLC service data unit that sends from the upper strata.Hereinafter, service data unit will be called SDU for short.
The scheduling of broadcast/group broadcast control (BMC) layer sent the cell broadcast messages (CB message) of coming from core net, and assists the UE of this information broadcast in the specific cell Already in.From UTRAN, CB message is sent from higher level, and provides the information such as message id, sequence number and encoding scheme extraly.CB message is delivered to rlc layer with the BMC message format, and is delivered to the MAC layer by logic channel (for example public service channel (CTCH)) subsequently.Logic channel CTCH is mapped to transmission channel (for example forward access channel (FACH)) and physical channel (for example Secondary Common Control Physical Channel (S-CCPCH)).
PDCP (PDCP) layer is positioned on the rlc layer and the data of transmitting by procotol (for example IPv4 or IPv6) can effectively be transmitted on the wave point with relatively little bandwidth.For this reason, the PDCP layer is convenient to reduce the unnecessary control information that cable network uses.This function is called header-compressed, can use by the Internet engineering duty group (IETF) definition such as RFC2507 or RFC3095 (healthy and strong header-compressed: header compression scheme ROHC).In these schemes, only the essential information (mandatory) of the header portion of data is transmitted, thereby reduced the data volume that to transmit by transmitting in a small amount control information.
Radio Resource control (RRC) layer is positioned on the 3rd layer the lowermost portion.Rrc layer only be defined within the chain of command and with the configuration of the radio bearer that is used for control logic channel, transmission channel and physical channel (RB), reconfigure and discharge and be associated.In this case, RB provides to the second layer to carry out the service of transfer of data between UE and UTRAN.Specifically, RB is that the layer 1 of wireless protocols and layer are 2 for carrying out the logical path that data delivery provides between UE and UTRAN.The configuration of RB is respectively processing that the characteristic that required protocol layer of special services and channel are provided is adjusted and to their special parameter and the processing set of method of operation.
Rrc layer comes broadcast system information by Broadcast Control Channel (BCCH).Be used for a system information of subdistricts and be broadcast to UE by system information block (SIB) form.Under the reformed situation of system information, UTRAN sends to UE by paging channel (PCH) or forward access channel (FACH) with BCCH modification information, receives up-to-date system information to impel UE.
Multi-medium broadcast/group broadcast service (MBMS) is described below.MBMS uses downlink-dedicated MBMS carrying service to provide stream service or background service to a plurality of UE.MBMS comprises at least one session.During carrying out session, the MBMS data are sent to a plurality of UE by MBMS carrying service.UTRAN uses radio bearer (RB) to provide MBMS carrying service to UE.Point-to-point radio bearer is the double-direction radio carrying and comprises logic channel DTCH (service-specific channel), transmission channel DCH (dedicated channel) and physical channel DPCH (DPCH) or physical channel SCCPCH (Secondary Common Control Physical Channel).The point-to-multipoint radio bearer is a uni-directional downlink.The point-to-multipoint radio bearer comprises logic channel MTCH (MBMS service channel), transmission channel FACH (forward access channel) and physical channel SCPCH.For each the MBMS configuration logic channel MTCH that offers the sub-district, and use logic channel MTCH to send the user face data relevant with specific MBMS to a plurality of UE.
Fig. 3 is an illustration is used for receiving by terminal the figure of embodiment of the channel Mapping of point-to-multipoint service.
With reference to Fig. 3, logic channel MCCH (MBMS control channel) is the point-to-multipoint downlink channel, and is used to send the control information that is associated with MBMS.Logic channel MCCH is mapped to transmission channel FACH (forward access channel), and transmission channel FACH is mapped to physical channel SCCPCH (Secondary Common Control Physical Channel).There is at least one MCCH in the sub-district.
Provide the UTRAN of MBMS MCCH information to be sent to a plurality of UE by the MCCH channel.MCCH information comprises the notice message (the RRC message that for example is associated with MBMS) that is associated with MBMS.For example, MCCH information can comprise the announcement that MBMS information is provided message, provide the point-to-multipoint radio bearer information announcement message and/or the access information of the announcement that connects at specific MBMS request EEC is provided.
Fig. 4 is an illustration according to the figure of the protocol stack structure of the HS-DSCH of prior art.HS-DSCH comprises the long transmission time interval (being called " TTI " hereinafter) of 2ms with three time slots.HARQ (mixed automatic retransmission request) scheme is used to HS-DSCH.AMC (adaptive modulation and coding) scheme also is used to HS-DSCH, selects the combination of only modulation and coding method to obtain optimal throughput at current channel circumstance.
With reference to Fig. 4, the data cell that will come from the rlc layer transmission of SRNC by logic channel DTCH or DCCH passes to the MAC-d entity of managing transmission channel, passes to the MAC-HS entity of Node B then by the MAC-c/sh/m entity of CRNC.MAC-d, MAC-c/sh/m and MAC-hs are respectively the MAC entities of management transmission channel, common signal channel and HS-DSCH.
